Hard Evidence Case 4 question

SPOILER WARNING:

I've got a question with case 4. A previous time when I ran through it, Doc Robbins told me (with accompanying movie) just how the victim botched his wife's eye surgery.

However, on replaying it right now, trying to get Master, no matter when I talk to him, I can't get that question; "Is it possible the wife could see?" to appear again. He just keeps telling me he has nothing more to tell me.
